Inspiration is everywhere!

A quick stop at The Antique Warehouse in Hudson, NY reminded us why we’re always on the hunt for unique pieces. With 3,000+ antiques and architectural treasures, every corner sparked a new idea.

At THI, it’s these one-of-a-kind finds that help us create spaces full of character and timeless style. Stay tuned to see what’s next!

January can feel a little… bland.
But your home doesn’t have to.

A fresh project—whether it’s a butler’s pantry refresh, better storage, upgraded lighting, or a simple re-style—can make everyday life feel elevated again …

If you’ve been thinking “after the holidays…” — this is your sign.
Let’s make your home feel inspiring all winter long.






DM us “JANUARY” to start your project.

Hi, I’m Theresa — the designer behind THI.
With so many new faces here, it felt like the perfect moment to reintroduce myself and share a little more about the philosophy behind my work.
At THI, we create livable luxury for clients across the Chicago region, Lake Geneva, and in exceptional lakefront and coastal destinations from coast to coast.
As a full-service interior design firm of 10 years, we specialize in deeply personalized environments that honor architecture, elevate everyday living, and reflect the stories of the people who call them home.
My work is rooted in a love for historic homes, fine craftsmanship, and the balance between timeless elegance and modern comfort. Whether designing a North Shore residence, a serene lakeside retreat, or a coastal getaway, my goal is always to create spaces that feel collected, intentional, and beautifully lived-in.
This past year brought especially meaningful milestones — from designing spaces for the 2025 Lake Forest Showhouse, to being featured in Cambria Style Magazine, and having THI highlighted in Veranda Magazine — and the many meaningful, thoughtfully crafted projects in between. I’m grateful every day for the clients who trust me with their homes and the artisans and partners who help bring each detail to life.
If you're new here, welcome.
If you’ve been here a while, thank you for being part of this community.
Here’s to a beautiful year ahead — and to the spaces that shape how we live.
— Theresa
